Improvement in combination-padlocks



UNITED EMIL R. J. LIIPOLD, OF FALLS CITY, NEBRASKA.

IMPROVEMENT IN COMBINATION-PADLCCKS.

Specification forming part of Letters Patent No. 149,766, dated April 14, 1874; application filed March 14, 1874.

To all whom it may concern Be it known that I, EMIL B. J. LIPPOLD, of Falls City, in the county of Richardson and State of Nebraska, have invented a new and valuable Improvement in Locks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this speciiication, and to the letters and iigures ot' reference marked thereon.

Figure 1 of the drawings shows a longitudinal section of my lock. Fig. 2 shows a side elevation of the same. Fig, 3 shows a transverse section, and Fig. 4 a detail view of the same.

This invention has relation to permutation hasp-locks; and it consists in constructing the barrel of the lock, to which the hasp or shackle is hinged, of several rotary sections with slotted diaphragms, the slots of which are adapted to receive through them a notched bolt, having a closing cap formed on one end, so that when the said bolt is inserted through all the diaphragms, and they are turned about their axes, they will enter the notches in the bolt and lock it securely in the barrel. It also consists in a slotted spring-cap, adapted to receive through it the said bolt, and also to receive a hook or catch on the free end of the hasp. It furthermore consists in a secret catch for the bolt, which, together with the features above referred to, will be hereinafter explained.

In the annexed drawings, A designates the barrel of the lock, B the hasp or shackle, and C the bolt. The barrel A is composed of several short sections, a, a head, D, and a foot or end section, b, which latter has hinged to it one end of the hasp B. The sections a are constructed with annular raised portions on their ends, and connected together, so that they can be rotated about their axes independently of each other. Between each section a is a diaphragm, c, loosely connected thereto.

by means of the raised and overlapping portion ed, through which diaphragms oblong slots c are made of equal length and width. The head D consists ot two circular plates, applied rigidly to a short barrel, through which is an opening, o, to receive the free end of the hasp B. The hole in this hasp, to-

gether with holes made through the two end plates of said head D, are of the same shape and size as the slots c through the diaphragms c. The head D is applied loosely, but not removably, in one end of the barrel A, and acted on by a helical spring, s, which keeps this head out in the position shown in Fig. 1. A slot, c', is made through the inner end plate of the head D for the purpose of receiving a lip, j which is formed on the free end ot' the hasp B, and thus making a latch for the hasp, which will hold it in place after the bolt C is removed. To release the free end of the hasp from the head D, after the bolt is removed trom the lock, it is only necessary to apply a slight pressure with the iingers on the head and move it into the barrel A until the lip j is free from the slot t'. The bolt C consists of wings c c, formed on a stem, and separated by notches or spaces c, as shown by Fig. 4. The number of notches c correspond to the number of diaphragms c, and the shape and size of the bolt in crosssectiou are like the shape and size of the slots through which it is passed. On the outer end of this bolt C a cap, C', is formed, which is constructed to receive` one end of the barrel A and the free end of the hasp B, when the bolt is in the position shown inv Fig. l. The cap C will thus close the end of the barrel when the hasp is locked. In order to introduce the bolt C, the slots through the diaphragms, through the head D, and through the end of the hasp B, must all be brought inline with each other. This is done by certain arbitrary marks on the peripheries of the several raised portions a/ of the diaphra gms c, which marks, on being adjusted in a line with each other, will indicate that the slots above referred to are all in line. After adjusting the diaphragm s, as described,

the lock is held with its hasp down, for the purpose of allowing a secret catch, el, to drop free from the notch c', which is next to the cap C. The bolt G can then be withdrawn from the barrel. When the bolt U is detached from the lock, the head D is exposed, and by pressing in this head so as to release it from the lip j on the free end of the hasp B, this end of the hasp can be released from its end of the barrel A. After the bolt C is introduced into the barrel A it can be locked therein by turning` any one or more of the overlappin gv portions a', which will adjust their diaphragms cinto the notches e of the bolt.

`What I claim as new, and desire to secure by Letters Patent, is-

1. The barrel A composed of sections a and slottedl diaphragins c connected together so that they can be rotated independently of each other, in combination with a notched and winged bolt, G, and a hasp, B, the free end of which is slotted, substantially as described.

2. The spring-head D, slotted as described, in combination with the slotted and lipped hasp B, and the sectional barrel A, substantially as set forth.

3. The secret catch d, combined with the sectional barrel A, the notched bolt C, and the hinged hasp B, substantially as described.

In testimony that I claim the above I have hereunto subscribed ny name in the presence of two witnesses.
